Abstract
[Technical Problem] To provide a method for manufacturing that enables to obtain a targeted glycopeptide harboring a sialyl sugar chain in high yield without decomposing sialic acid at a non-reducing terminal of sugar chain when the glycopeptide is synthesized by a Boc solid phase synthesis method. [Solution to Problem] The present invention is characterized in that the Boc-sialylglycosylated amino acid derivative used in Boc solid phase synthesis method is one where the carboxyl group of the sialic acid at the sugar chain non-reducing terminal is protected with a phenacyl group.
